Roy W. Miller (roy@roywmiller.com), Programmer, Independent

Roy Miller is an independent software development coach, programmer, and author. He began his career at Andersen Consulting (now Accenture), and most recently spent three years using Java professionally at RoleModel Software, Inc. in Holly Springs, NC. He has developed software, managed teams, and coached other programmers at clients ranging from two-person start-ups to Fortune 50 companies.

Summary: The Java™ language provides most of what professional programmers expect to see in a language, and even in an object-oriented language. Beyond the basics, though, the Java language provides some useful tools for creating sophisticated programs. This tutorial will introduce you to some of these more advanced Java language features commonly seen on typical Java technology development projects.

About this tutorial

This tutorial introduces you to capabilities of the Java language that are more sophisticated than those covered in the "Introduction to Java programming" tutorial (see Resources for a link to this and other material referenced in this tutorial). In order to get to the most out of this tutorial, you should have completed that introductory tutorial, or be familiar with the concepts covered in it.

The Java language provides a vast set of tools that can help a programmer accomplish almost any task. In this tutorial, we'll cover a few of the more advanced tools that are commonly used on Java development projects, including the following:

Inheritance and abstraction
Interfaces
Nested classes
Regular expressions
Collections
Dates
I/O

Prerequisites

The content of this tutorial is geared toward moderately experienced Java programmers who might not be familiar with some of the more involved features of the language. It assumes a general knowledge of downloading and installing software, and a general knowledge of object-oriented programming (OOP) with the Java language. You might not use the more advanced Java language features we'll talk about here in every application -- in fact, you probably shouldn't -- but it's wise for a professional programmer to know about them and be able to use them when appropriate.

In addition to familiarity with the concepts covered in the "Introduction to Java programming" tutorial see Resources), you'll need to have the following installed to run the examples or sample code in this tutorial:

JDK 1.4.2 or higher (5.0 recommended)
The Eclipse IDE

All code examples in this tutorial have been tested with JDK 5.0 on the Windows XP platform, but should work without modification using JDK 1.4.x. You can download source code for the tutorial from Resources. It's contained in intermediate.jar, which you can import into your Eclipse workspace.

The sample JAR file does not necessarily contain the code for every example in this tutorial in its final form. Instead, it contains the core of what we'll cover, minus some of the iterative modifications that we'll apply to the code as we progress through the article. Modifying the core to explore the language features we'll cover in this tutorial is left as an exercise for you.
